IHydroxypropyl Methylcellulose
IHydroxypropylMi-ethylcellulose (HPMC) noma i-hypromelloseiphuma kokunyes i-methyl cellulose ama-ethers. Ikonai-fibrous emhlophe noma emhlophe noma i-granulari-cellulose etherimpushana. Njengamanje i-cellulose ama-ethers ngokusebenza okuhle kakhulu emhlabeni, okuhlanganisa ukujiya, ukumisa okwesikhashana, ukuhlakaza, ukuqinisa kanye nokuzinzisa. I-Hydroxypropyl methyl cellulose (HPMC) ayinabo ubuthi, kulula ukuyisebenzisa, futhi incibilika kalula emanzini. Kuyi-polyanion kwisisombululo esinamanzi futhi inezinto ezibonakalayo eziyingqayizivele. Ukusebenza okuqondile ngu njengoba ngezansi:

Izici:
1. Ukunyibilika: Cishe ayincibiliki ku-ethanol ephelele, i-ether ne-acetone, futhi incibilika ibe isixazululo se-colloidal esicacile noma esithuthuma kancane emanzini abandayo. Ingancibilika kwezinye izinyibilikisi zemvelo, futhi ingancibilika ku-solvent exubile yezincibilikisi zamanzi-organic.
2. Ukumelana nosawoti: Kuzinzile uma kuqhathaniswa nezixazululo ezinamanzi lapho usawoti wensimbi noma ama-electrolyte ephilayo ekhona.
3. Umsebenzi ongaphezulu: ungasetshenziswa njengesivikelo se-colloid, i-emulsifier ne-dispersant.
4. PH-ukuzinza: PH inani lizinzile kububanzi obungu-3.0~11.0. I-viscosity yesisombululo esinamanzi ayithintwa neze i-asidi noma i-alkali.

Isebenzisa ye-HPMC:
Hi-ydroxypropyl methylcellulose(HPMC) ingasetshenziswa njenge-thickener, dispersant, emulsifier, kanye ne-ejenti yokwenza ifilimu, njll.UkwakhaIbanga I-HPMC imikhiqizo ingasetshenziswa amakhemikhali nsuku zonke, electronics, zokwenziwa resin, ukwakhiwa kanye ezinengilazi, grade imithi I-HPMC ingasetshenziswa kuenamathela tablet, njll., kanye nebanga lokudla I-HPMC ingasetshenziswa njengezithasiselo zokudla ezihlukahlukene.
Umhlahlandlela we-HPMCImiyalelo:
1. Indlela yamanzi ashisayo: Faka u-1/3 noma u-2/3 wamanzi esitsheni bese uwashisisa abe ngaphezu kwama-80. I-hydroxypropyl methyl cellulose yokuqala(HPMC) ingahlakazwa ngokulinganayo emanzini ashisayo, bese wengeza inani elisele lamanzi abandayo ku-slurry yamanzi ashisayo, epholile ngemva kokugqugquzela.
2. Indlela yokuxuba impushana: hlanganisa i-hydroxypropyl methyl cellulose(HPMC) impushana enenani elikhudlwana lezinye izithako eziyimpuphu, ihlakaze kahle ngokuxuba okomile, bese ufaka amanzi ukuze uyincibilikise..
3. Indlela yokumanzisa i-organic solvent: qala uhlakaze noma manzise i-hydroxypropyl methyl cellulose (HPMC) nge-solvent ephilayo, bese ufaka amanzi ukuze uyincibilikise.
